Forticlient vpn linux ubuntu

Подключение Linux Ubuntu 20.04, 20.10, 21.04 к Forti VPN

Предыстория

Так уж получилось, что для удаленного доступа к работе приходится использовать Forti VPN.

В Windows за подключение отвечает отдельное приложение, а в Ubuntu 18.04 раньше использовал пакет из репозитория openfortivpn и GUI клиент с сайта https://hadler.me/linux/openfortigui/ .

Интерфейс OpenFortiGUI

Не феншуйно, но работало. Времени искать более правильное решение не было.

Сейчас, когда только-только вышла Ubuntu 20.04 работающего без ошибок GUI Forti VPN клиента еще не выпустили.

Прежде всего в репозитории я нашел для GNOME пакет network-manager-fortisslvpn-gnome. В результате его установки в настройках подключения появился пункт настройки VPN и возможность выбора типа подключения.

Добавление нового подключения Fortinet VPN

Безусловно это вселяло надежду, что получится отказаться от громоздкого GUI приложения.

После создания и настройки нового подключения появляется соответствующий пункт в панели управления.

Но вот незадача, не подтягиваются DNS сервера от DHCP сервера. После многих часов поиска ответа на вопрос что же происходит привели меня к следующему выводу. Оказалось, что наш VPN-cервер Forti использует SSL для шифрования, а его использование по умолчанию отключено в systemd.

Решение

Итого, чтобы настроить подключение к Forti VPN с шифрованием SSL и корректным использованием DNS серверов нужно:

1 — Установить network-manager-fortisslvpn-gnome

sudo apt-get install network-manager-fortisslvpn-gnome

2 — Открываем файл /etc/systemd/resolved.conf . Далее ищем строчку DNSOverTLS, раскомментируем ее и присваиваем значение opportunistic. Потом раскомментируем строку Domains и прописываем доменное имя DNS-сервера. После чего дописываем DNS.

[Resolve]
DNS=X.X.X.X
DNS=Y.Y.Y.Y
#FallbackDNS=
Domains=corp.yourdomain.com
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
DNSOverTLS=opportunistic
#Cache=yes
#DNSStubListener=yes
#ReadEtcHosts=yes

3. Перезапускаем systemd

sudo systemctl daemon-reload
sudo systemctl restart systemd-networkd
sudo systemctl restart systemd-resolved

Затем переподключаем соединение или для избежания доп проблем вообще перезагружаемся.

Все, при новом подключении к VPN серверу DNS серверы должны начать использоваться системой.

Альтернативное решение

Есть всегда альтернативный способ прописать DNS-серверы вручную и для этого нужно:

1 — Установить resolvconf

sudo apt-get install resolvconf

2 — Затем открыть один из файлов в папке /etc/resolvconf/resolv.conf.d (head или tail)

3 — После чего прописать в файл информацию о DNS серверах.

Forticlient – SSLVPN .deb packages

Forticlient – SSLVPN is a VPN Client to connect to Fortigate Devices with minimal effort, packaged here for Ubuntu and Debian.

Officially there is only a generic tar.gz package available. As I use Ubuntu most the time, I decided to build .deb packages for 32/64bit Ubuntu with a nice desktop icon to start : )

This packages should also work on debian, but i did not test this on myself now (will follow).

For upgrades just download the new package and install it, the package manager will do the upgrade for you.

I will share my packages here for you to download:

it’s been a while since I left comment on blog post 🙂
But this deb package is working on linux mint 20.2

It’s perfect, it works on Debian 10 without any problem. Thank you, God bless you.

Wood home furniture has one thing very natural regarding it.
There is this sense of comfort, of nature and of luxury that could be be
found in hardwood furnishings. Hardwood is birthed coming from the earth.
It feeds the fire, degenerates in to ashes and blows away.
It is actually extremely near the human presence in the world.
May be actually that is why it reverberates so much with us.
When you handle a rich mahogany work desk, might be actually that is why you still get
that warm sensation.

Nice work. But I have a problem when there is a lot of data to transport over the VPN. It looks like the VPN limits the datastream to 15-16Mbit/s. Is there a way to change this limit? I use a RD and need to check remote camera’s. I tried other RD clients. No difference. So it must be the VPN client.
Thx.

thank you so much 😀 its work for my on Ubuntu 20.4

forticlient not working on ubuntu 20.4 .Please give me a solution.

Thankou. saved me….

thank you SO MUCH!! (ubuntu 18.04)

I’m installed this .deb package on debian 10 but setup failed!!

The problem occurs because ldconfig is inside /sbin and since debian 10 is not going up the directory within the PATH variable, it generates this problem. To fix it, just open the /etc/profile file and add /sbin after games, making it like this:
==
PATH=”/usr/local/bin:/usr/bin:/bin:/usr/games/sbin”
==

Then just give a command source in file /etc/profile file and run dpkg -i with .deb.

And don’t forget to insert your user in sudoers file, to exec the app, because per default in installation the debian don’t insert users in sudoers file.

Sob! Doesnt work on ARM, would love to have a version compiled and installable on Raspberry Pi Debian.

sudo dpkg -i forticlient-sslvpn_4.4.2333-1_i386.deb
dpkg: error processing archive forticlient-sslvpn_4.4.2333-1_i386.deb (–install):
package architecture (i386) does not match system (armhf)

Suddenly, I have the following error: OpenSSL: error:1409442E:SSL routines:ssl3_read_bytes:tlsv1 alert protocol version.
(it has worked for months before this error)

SSL VPN: Configuring and Using Forticlient on Ubuntu, creating a Launcher

1. Is your primary OS at home Linux and do you use Windows only to connect to your work PC over VPN or to attend meetings?
2. Do you often wish to connect to your work VPN from a Linux PC?

Obtaining Forticlient

Using Forticlient

Files Extraction

Once you have the file (the name would be forticlientsslvpn_linux_ .tar.gz), extract it to the location of your choice on your Linux PC (I’m on Ubuntu 16.04 LTS).

Launching

You can launch the Forticlient using the terminal after navigating to the path. You need to launch the script as superuser only the first time you run it.

Accept the license agreement and you will have the client running immediately after that —

Enter the details provided by your administrator in terms of the URL, port number etc. and click connect to establish the connection. If you don’t use a certificate you can leave the fields blank. A warning dialog to this effect would be shown while connecting on which you can click ‘Continue’.

To avoid entering details every time, you can save the connection details which will persist between sessions. Click ‘Settings’ for this —

Connecting to the remote computer

Click on ‘New’ and save your machines details. You can select various color depth values; quality, sound (in Advanced tab) to improve your connection experience.

Once done, click ‘Connect’.

Creating a Unity Launcher

Create a .desktop file which will act as a launcher with the following content.

You can pin the launcher to Unity Launcher if necessary.
